Optimal investment and contingent claim valuation in illiquid markets
نویسنده
چکیده
This paper extends basic results on arbitrage bounds and attainable claims to illiquid markets and general swap contracts where both claims and premiums may have multiple payout dates. Explicit consideration of swap contracts is essential in illiquid markets where the valuation of swaps cannot be reduced to the valuation of cumulative claims at maturity. We establish the existence of optimal trading strategies and the lower semicontinuity of the optimal value of optimal investment under conditions that extend the no-arbitrage condition in the classical linear market model. All results are derived with the “direct method” without resorting to duality arguments.

On General Equilibrium Effects and Contingent Claim Valuation of Financial Assets
This paper studies the extent of the error that is made in standard contingent claim analysis, which underlies modern asset pricing theories and real option theory within a two-period general equilibrium model with incomplete markets. It is well-known that in mean-variance, or CARA-normal economies the introduction of new assets leaves the prices of existing assets, relative to the bond, unchan...
متن کاملA consistent stable numerical scheme for a nonlinear option pricing model in illiquid markets
Markets liquidity is an issue of very high concern in financial risk management. In a perfect liquid market the option pricing model becomes the well-known linear Black-Scholes problem. Nonlinear models appear when transaction costs or illiquid markets effects are taken into account. This paper deals with the numerical analysis of nonlinear Black-Scholes equations modeling illiquid markets when...
متن کاملForward Exponential Performances: Pricing and Optimal Risk Sharing
In a Markovian stochastic volatility model, we consider financial agents whose investment criteria are modelled by forward exponential performance processes. The problem of contingent claim indifference valuation is first addressed and a number of properties are proved and discussed. Special attention is given to the comparison between the forward exponential and the backward exponential utilit...
متن کاملLiquidity Preference under Uncertainty: a Model of Dynamic Investment in Illiquid Assets
The paper presents a mathematical model of optimal investment in illiquid assets. Specifically, the model addresses the problem of an investor with limited capital resources, who makes sequential decisions on long-term investments under uncertainty as to future opportunities. The model demonstrates that such an investor will optimally demand a higher rate of return on investments in long-term, ...
متن کاملArtificial Neural Networks for Valuation of Financial Derivatives and Customized Option Embedded Contracts
In this paper we propose and test a valuation methodology for improving the efficiency of contingent claims pricing using Artificial Neural Networks (ANN). Contingent claims is by now a standard method for pricing under uncertainty nonlinear (option embedded) contracts, for both financial options (standardized or customized) and real (investment) opportunities. In the presence of liquid option ...
